Coffee reduces the risk of liver cancer by half

Scientists from the Universities of Southampton and Edinburgh studied data from 26 previously conducted studies, in which a total of about 2.25 million people participated.
Compared to people who didn't drink coffee, those who drank one cup a day had a 20% lower risk of developing cancer. For those who consumed two cups a day, the risk was reduced by 35%, and for those who drank five cups, the risk was halved. The protective effect of decaffeinated coffee was less pronounced, but also obvious. The scientists described these and other results in an article published in BMJ Open (Kennedy et al., Coffee, including caffeinated and decaffeinated coffee, and the risk of hepatocellular carcinoma: a systematic review and dose–response meta-analysis).

"Coffee is believed to have a number of health benefits, and these latest findings suggest that it may have a significant impact on the risk of liver cancer," says lead author Oliver Kennedy. – We do not suggest that everyone should start drinking five cups of coffee a day. Additional research is needed on the potential harm associated with caffeine. There is also evidence that its use should be avoided in certain groups, such as pregnant women."
"We have shown that coffee reduces cirrhosis and liver cancer in a dose–dependent manner," adds study co-author Professor Peter Hayes. – Earlier it was reported that coffee reduces the risk of death from many other causes. We have proven that in moderation coffee can be a wonderful natural medicine."
The authors believe that the results obtained are important, given the growing incidence of hypatocellular liver cancer worldwide and the unfavorable prognosis of its development.
Hepatocellular cancer is the most common cancer of the liver, which affects the epithelial cells of the hepatic lobule (hepatocytes). The disease is widespread throughout the globe and accounts for 84-89% of all oncological processes in the liver. Annually, hepatocellular cancer is diagnosed in 600 thousand inhabitants of the planet.
